12 Claims. (Cl. 12--33.6)

This invention relates to sole attaching presses, and is illustrated herein as embodied in a two-station machine adapted to position a pair of soles in register with the bottoms of a pair of slip-lasted platform shoes and to attach them thereto in a single cycle of operations. It is to be understood, however, that in various of its novel aspects the invention is not thus limited as to its utility.

The bottom of a slip-lasted platform shoe of the socalled casual type, which has enjoyed great popularity in recent years, usually embodies, in addition to a platform sole, a wedge heel of varying height and pitch. To this shoe bottom is attached by cement an outsole, commonly made of a synthetic material and pre-fitted for the particular size and style of shoe to which it is to be attached. According to current practice, the shoes and soles are carried on separate racks to the sole attaching press, where the soles are pre-spotted, that is, located in register with the shoe bottoms and pressed against them at two or more spots, usually at the toe and heel ends, to hold them in place until they are introduced into the attaching press. This operation is performed by hand, either by the operator of the attaching press or by a special operator stationed alongside the operator of the attaching press. It will be readily appreciated that such preliminary spotting necessarily results in slowing the rate of producticn and increasing manufacturing costs. Moreover, since this operation is performed by hand, there is a substantial margin for error in the assembling of soles and shoes, and since there is no mechanical control of the sole and shoe after they have been thus spotted, there is no assurance that they will be maintained in register until they are permanently bonded together.

An object of the present invention is to eliminate the separate preliminary manual pre-spotting of outsoles to shoe bottoms, and to provide instead an arrangement whereby such pre-spotting is performed mechanically and automatically in the same machine in which the soles are attached to the shoes and in the course of a single cycle of operations, and in which the soles and shoes are maintained under control throughout the cycle of operations of the machine.

With this object in view and in accordance with a feature ofthe invention, there is provided a machine adapted to attach a pair of soles at a time, and having means for supporting a pair of shoes in inverted position, means constructed and arranged to engage the toe and heel ends of each shoe and of a sole placed on the bottom thereof to position the sole and shoe in register with each other, and to maintain them in registered relation throughout a cycle of operations of the machine, locking means for clamping each shoe on its supporting means prior to en gagement of the positioning means with the opposite ends of the sole and shoe, pressure applying means for pressing the two soles against the shoe bottoms, means for automatically ejecting the shoes from the machine at the end of an attaching cycle, and single power- 2,896,233 Patented July 2 8', 1959 operated means for controlling the movements of the positioning means into and out of engagement with the soles and shoes at both operating stations, and for also controlling the operation of the shoe locking means, the pressure applying means and the shoe ejecting means.

The supporting means comprises at each operating station a post for the heel end and a post for'the toe end of the shoe. The heel post is formed integral with a carrier slidably mounted in a casting of the machine and supports at its upper end a bracket in which a block is slidably mounted. The block supports a rocker member carrying a spindle arranged to engage in the thimble in the heel of a last. The toe post is similarly formed integral with a carrier slidably mounted in a casting of the machine and supports a bracket inwhich is slidably mounted a block carrying a toe pad. In accordance with another feature of the invention, the machine is provided with means for simultaneously adjusting the heel posts at the two stations heightwise to locate shoes having heels of various heights in the proper position relative to the heel end positioning means, and similar means for simultaneously adjusting the toe posts at the two stations in the same direction relative to the toe end positioning means. The machine is further provided with I means for adjusting the slidable blocks of the heel end and toe end supporting means at the two stations lengthwise of their brackets, to vary the positions of the last spindle carrying rocker members and the toe pads in accordance with variations in shoe sizes. Means is also provided for varying the angular positions of the rocker members at the two stations simultaneously in order to locate the spindles carried by them at angles corresponding to the angles of the thimbles in the heels oflasts for shoes of different styles, so that the lasts .will be properly seated against the top surfaces of the rocker members.

As herein illustrated, the means for positioning a sole in register with a shoe at each station comprises a heel end embracing gage and a toe end embracing gage. Each gage is carried by a parallel linkage connected to and actuated by a pair of parallel arms which are in turn connected to a power-operated main lever. The parallel arms which actuate the heel end gage mechanism are pivoted in a bracket secured to the carrier for the heel end supporting means. The parallel arms which actuate the toe end gage mechanism are similarly pivoted in a bracket which is connected to the carrier for the toe end supporting means. In accordance with an important feature of the invention, the machine is provided with pantographing means for effecting simultaneous relative adjustment of the carriers for the heel and toe end supporting and positioning means, so that, after having made the adjustments above referred to for positioning shoes of a mean size at the correct height and angle, the shoe supporting means and the heel and toe gages will be properly located for operating on shoes of various sizes;

To guard against shifting of the shoes on their supporting means when the gages are moved into engagement withthe heel and toe ends of the soles and shoes, there is provided, in accordance with another feature of the invention, means for. locking or clamping the shoes against the toe pads at the two stations. The shoe locking means is actuated by the previously mentioned power-operated main lever during its operative movement to move the gages into engagement with the soles and shoes. To insure that the locking means will be operated before the gages, a 10st motion is provided in the connection between the gage actuating parallel arms and the main lever.

For pressing the soles against the shoe bottoms there are provided pressure pads mounted in pad boxes supported by a carried or yoke pivoted on arms fulcrumed on the opposite ends of a pressure equalizing lever or whiflletree actuated by the power-operated main lever. The pad boxes are arranged for rocking movements lengthwise of the shoes, and the pad box carrier is arranged for rocking movements laterally of the shoes.

'Safety means is provided, according to the invention, for requiring the operator to employ both his hands to start an operating cycle and until the pressure pads have been moved into a position in which he cannot put his hands into the machine. Other safety means, actuated by the pressure of the toe ends of the shoes in the two stations when clamped against the toe pads by the shoe locking means, prevent operation of the gages and of the pressure pad boxes unless there is present a shoe in each station of the machine and unless both shoes have been clamped by their locking mechanisms.

Means is also provided, in accordance with a still further feature of the invention, for automatically ejecting the shoes after the attachment of the soles. The ejecting means is operated at the beginning of the return movement of the main lever at the end of a predetermined cycle of operations of the machine, immediately after the gages have been moved out of engagement with the shoes.

These and other features and advantages of the invention will be more fully explained in the description Which follows, in conjunction with the accompanying drawings, and particularly pointed out in the claims.

The machine embodying the invention is herein illustrated as a two-station machine adapted for the automatic and simultaneous positioning of a pair of soles relatively to a pair of shoes placed in the two stations and the cement attachment of the soles to the bottoms of the shoes. The two stations are identical. Accordingly, when the parts and mechanisms appertaining to a station are described, it should be understood that these parts and mechanisms are duplicated at the other station. The machine is also provided with certain mechanisms essential to the simultaneous operation of the two stations and therefore common to both stations. Such mechanisms, as will appear more particularly in the following description, include a common carrier for the two pressure pads, a single main lever for operating the positioning and attaching mechanisms of both stations, a single hydraulic piston for actuating the main operating lever, and common electrical controls for operating the machine.

The machine comprises a base 20 (Figs. 1, 3 and 4) to which are bolted two castings 22 each carrying worksupporting and positioning means generally indicated by the reference numeral 24 for the heel end of a shoe, and substantially similar work-supporting and positioning means generally indicated by the reference numeral 26 for the toe end of the shoe.

Work-supporting mechanism The heel-end supporting and positioning means at each station is mounted on an inclined carrier 28 guided in ways in the casting 22 and retained therein by bars 29 bolted to the casting. A vertically extending post or screw 30 is mounted for heightwise adjustment in a cylindrical housing 32 integral with the carrier. A plate or bracket 34 integral with the top of the screw 30 is provided with a guideway in which is slidably mounted a block 36. The block 36 is formed with a concave recess in which is adjustably mounted a rocker 38 held in the block 36 by side plates 40. The rocker 38 carries a last spindle 42 adapted to engage the thimble in the heel of a last L supporting a shoe S to which an outsole O is to be attached.

The toe end supporting and positioning means is mounted on a substantially horizontal carrier 44 mounted for adjustment forward or rearward of the machine in a guideway formed in the casting 22, the carrier being retained in the guideway by bars 45 bolted to the top of the casting. A vertically extending post or screw 46 is mounted for heightwise adjustment in a cylindrical housing 48 integral with the carrier. A bracket or plate 59 formed integrally with the top of the post 46 is provided with a guideway in which a slide 52 is mounted for longitudinal adjustment relatively to the bracket 56. A toe rest block 54 has a dovetail portion 56 engaging in a dovetail groove in the slide 52 to permit adjustment of the block 54 laterally of the slide to locate it in the desired position for engagement with the toe portion of the shoe. The toe rest block 54 is covered with a pad 58 of resilient material.

Adjustment of heel and toe and supporting means The heel posts 30 at the two stations may be adjusted simultaneously heightwise to vary the position of the last pin 42 in accordance with variations in heel height. For this purpose there is threaded on each heel post a sprocket wheel 60, the two wheels being interconnected by a sprocket chain 62 whereby the wheels may be turned to raise or lower the posts 30 to the desired positions.

The toe posts 46 at the two stations are similarly adjustable heightwise to vary the positions of the toe pads 58 in accordance with variations in the thickness of the toe, or of the platform sole of a platform shoe.

To this end there is threaded on each toe post 46 a sprocket wheel 64, a sprocket chain 66 being mounted on the two wheels whereby these may be rotated simultaneously to raise or lower the toe posts to the desired positions.

Provision is also made for simultaneous adjustment of the blocks 36 which support the last-spindle-carrying rockers 3:3 lengthwise of the brackets 34 to aline the center of the bottom of a shoe mounted on each last spindle with the axis about which a pad box (to be detapped hole provided in the forward end of the block 36. A shoulder 72 on the screw 68 abuts against the inner side of the plate 70, the outer side of which is engaged by a collar 74 pinned on the screw. On the outer end of the screw 68 is mounted a sprocket wheel 76. A sprocket chain 78 interconnecting the two sprocket wheels 76 permits conioint rotation of the wheels and of the screws 68 for simultaneous adjustment of the blocks 36 at the two stations.

The slides 52 carrying the toe rest blocks 54 at the two stations also may be simultaneously adjusted lengthwise of their supporting brackets 50 to locate each toe pad 58 in a position corresponding to the tip line of the shoe. For this purpose a screw 80 extending through an end plate 82 secured to the bracket 50 is threaded into a tapped hole provided in the slide 52. A shoulder 84 on the screw 80 abuts against the inner side of the plate 82, while a collar 86 pinned to the screw aJb-uts against the outer side of the plate. A sprocket wheel 88 is mounted on the outer end of the screw, and a sprocket chain 90 mouned on the two sprocket wheels 88 permits conjoint rotation of the wheels 88 and the screws 80 for simultaneous adjustment of the slides 52 at the two stations.

Referring to Figs. 3 and 6, the rocket 38 at each station is normally adjusted in an angular position in which the last pin 42 carried -by the rocker is disposed at an angle corresponding to the angle of inclination of the thimble in the heel of the last with respect to the shoe bottom for shoes of a particular style. For varying the angular positions of the rockers to accommodate lasts for shoes of different styles, there is provided at each station of the machine a screw 92 extending at an angle through the rear end wall of the block 36 and through a recess 94 in the lower surface of the rocker 38. Pins 96 extending inwardly from the side walls of the rocker which define the recess 94 are arranged to maintain the rocker in the adjusted angular position by engagement with a collar 98 on the shank of the screw. By turning the screw 92 the rocker 38 may be tilted clockwise or counterclockwise to the desired angular position. For turning the screws 92 at the two stations simultaneously to effect the simultaneous adjustment of the two rockers 38, a sprocket wheel 100 is mounted on the outer end of each screw, the two sprocket wheels being interconnected by a sprocket chain 102. A compression spring 104 (Fig. 6) on the forward end of each screw 92 bears against the collar 98 on the screw and permits the rocker 38 to tilt yieldingly in an upward or counterclockwise direction under pressure exerted on the heel end of a shoe in the event the heel of the last is not properly seated on the top surface of the rocker 38.

The machine is further provided with pantographing means for simultaneous relative adjustment of the heel and toe end supporting and positioning means for operating on shoes of various sizes. Referring to Fig. 3, the inclined carrier 28 at each station of the machine has depending therefrom a lug 106 to which is pivotally connected one end of a link 108, the other end of which is pivotally connected to one end of a lever 110 pivoted intermediate its ends on a pin 112 mounted on the machine base 26. The other end of the lever 110 is pivotally connected by a link 114 to one arm of a bell crank lever 116 the other arm of which is pivotally connected to one end of a link 118, the other end of which is connected to the bifurated rear end of the carrier 44. A screw 120 passing through a block 122 secured to the casting 22 and threaded into the carrier 28 has mounted on its outer end a sprocket wheel 124. A sprocket chain 126 interconnecting the two sprocket wheels permits simultaneous rotation of the screws 120 at both stations for relative adjustment of the carriers 28 and 44 and of the work-supporting and positioning mechanisms carried by them.

Sale positioning mechanism Gage mechanisms of novel construction and operation are provided which are arranged to be moved into engagement with the toe and heel ends of a shoe mounted on the last spindle 42 at each station and with a sole placed on the bottom of each shoe, to position the soles in register with the bottoms of the shoes prior to the op eration of the pressure applying means to attach the soles to the shoe bottoms. Referring more particularly to Figs. 3, 4, 11 and 12, the heel end gage at each station comprises a U-shaped heel-embracing band 128, preferably of a plastic material, with a smooth work-engaging surface and with ribs 129 formed on the side opposite the work-engaging surface for strengthening the band. The band 128 is secured to blocks 130 by screws 132 which also secure the band to brackets 134 and to arms 136. The arms 136 are secured by screws 138 to arms 140 fulcrumed on pins 142 mounted in a bracket 144. In the bracket 144 is mounted a pair of parallel transverse shafts 146 to which are pivoted the inner ends of a pair of parallel links 148 the outer ends of which are pivoted on parallel transverse shafts 150 mounted in a bracket 152. A torsion spring 153 on the upper one of the pair of shafts 150 has one end bearing against the underside of the bracket 152, its opposite end bearing against a crossbar 154 of the upper link 148.

The assembly comprising the brackets 152 and 144 and the parallel links 148 operates in the manner of a toggle mechanism which, upon downward movement of the pressure applying means (to be described) to press the soles against the shoe bottoms, is moved from its broken position shown in Fig. 3 to the straightened position shown in Fig. 4, against the resistance of the spring 153 which returns the assembly to the broken position when released by the pressure applying means at the end of a sole-attaching operation. Tension springs 155, each attached at one end to a pin 156 extending from the bracket 144 and at its opposite end to one of the brackets 134, act to insure that the top of the heel-embracing band 128 will engage the heel ends of the shoe and sole first.

The toe end gage at each station comprises a U-shaped toe-embracing band 158 (Figs. 3, 4, 11 and 12) of plastic material with a smooth work-engaging inner surface and ribs 159 on its outer side to strengthen the band. The band is secured to blocks 160 by screws 162 which also secure the blocks 160to arms 164 fulcrumed on pins 166 mounted in a bracket 168. In the bracket 168 is mounted a pair of parallel shafts 170 on which are pivoted the inner ends of a pair of parallel links 172, the outer ends of which are pivoted on a pair of parallel shafts 174 mounted in a bracket .176. A torsion spring 178 surrounding the upper one of the pair of shafts 174 acts between the bracket 176 and the crossbar 180 of the upper link 172 to urge the links in a clockwise direction as viewed in Figs. 3 and 4. A cable 182 connects the bracket 176 and the carrier 44 for the toe end work supporting and positioning mechanism at each station, so that when the carriers 44 are adjusted forward or rearward with relation to the carriers 28 for the heel end work supporting and positioning mechanisms, in the manner described above, the toe embracing gages will be moved a corresponding amount to maintain them in the same relative positions with respect to the toe pads 58.

Gage operating mechanism The heel embracing gage 128 at each station is operated to move into and out of engagement with the heel ends of a shoe and a sole located thereon by mechanism comprising a pair of substantially parallel arms 184, 186 (Figs. 1, 3 and 4). The upper end of the arm 184 is pivotally mounted on the lower shaft 150, the lower end of the arm being pivoted on a shaft 188 mounted in a bracket 190 bolted to the inclined carrier 28. The upper end of the arm 186 is pivoted on a shaft 192 mounted in the bracket 152, the lower end of the arm being pivoted,

on a shaft 194 also mounted in the bracket 190. On the opposite ends of the shaft 194 are mounted friction clutch members 196 (only the outer one is shown in the drawings), the function of which will be explained hereinafter. A lever 198 fulcrumed on the shaft 194 has a pin-and-slot connection to the upper end of a connecting rod 200, the lower end of which is fulcrumed on a shaft 202 (Figs. 1, 2 and mounted in an upstanding lug 203 of a main operating lever 204 extending widthwise of the machine and fulcrumed at its opposite ends on pivots 206 (only one of which is shown in Figs..1 and 5) mounted in thebase of the machine.

The toe embracing gage 158 at each station is moved into and out of engagement with the toe ends of a shoe and sole located thereon by mechanism substantially similar to that just described for operating the heel end embracing gage 128. This mechanism comprises a pair of substantially parallel arms 208, 210 (Figs. 1, 3 and 4). The arm 208 is pivoted at its upper end on a shaft 212 carried by the bracket 176 and at its lower end on a shaft 214 mounted in a bracket 216 bolted to the base 20 of the machine. The arm 210 is pivoted at its upper end on a shaft 218 carried by the bracket 176 and at its lower end on a shaft 220 mounted in the bracket 216. On the opposite ends of the shaft 220 are mounted friction clutch members 222 similar to the clutch members 196. A lever 224 mounted on the shaft 220 has a pinand-slot connection to the upper end of a connecting rod 226, the lower end of which is pivoted on the shaft 202 (Fig. 2) mounted in the main operating lever 204. In a downwardly extending boss 228 (Figs. 1 and 5) of the lever 204 is journaled a shaft 230 on which is pivoted the lower end of an arm 231 the upper end of which is connected to a piston 232 housed in a cylinder 234 supported in the base 20 of the machine. The upper end of the cylinder is connected by a pipe 236 to a hose 238 (Fig. 1) connected to a source of pressure fluid, as willbe explained, to cause downward movement of the piston 232. A pipe 246 provides connection to the lower end of the cylinder to return the piston. The source of pressure fluid includes a reservoir or sump 240 and a pump 242 which is constantly driven by a motor M controlled by start and stop switches 244, 244 housed in a box 245 mounted on the machine frame.

When pressure fluid is supplied to the upper end of the cylinder 234, at the beginning of an operating cycle, downward movement of the piston 232 causes the main operating lever 284 to swing counterclockwise, as seen in Figs. 1 and 5, and through the connections comprising the rods 200 and 226, the levers 198 and 224 and the clutch members 196 and 222, causes the pairs of parallel arms 184, 186 and 208, 210 to swing inwardly relative to each other. By this movement of the arms the brackets 152, 176 to which they are pivoted are moved in a substantially horizontal direction relatively to each other to move the heel and toe embracing gages 128 and 158 at each station into engagement with the opposite ends of the shoe and the sole located thereon (see Fig. 6) to position the sole in register with the shoe bottom prior to the application of pressure to effect the cement attachment of the sole. During continued downward swinging movement of the operating lever 204 after engagement of the opposite ends of the shoe and sole by the gages 128, 158, the clutch members 196, 222 are rotated about the shafts 194, 220 in the same directions as those in which the arms 184, 186 and 208, 210 are swung and by their slipping action maintain the gages firmly but somewhat yieldingly in engagement with the shoe and sole, and take up the additional movement of the operating lever to actuate the pressure applying means, thereby preventing damage to the shoe and sole by excessive clamping action of the gages. At the beginning of the return movement of the operating lever after completion of an operating cycle of the machine, the same clutch members are rotated in reverse directions to retract the '8 gages promptly from the shoe to enable it to be ejected from the machine by mechanism to be described later. As more particularly illustrated in Fig. 6, when the gages 128, 158 embrace the heel and toe ends of the outsole 0, they cause the outsole to bulge upward. This is due to the fact that the sole is somewhat longer than the shoe bottom in order to provide the extra length necessary to fill the cavity in the shank portion of the shoe. During the sole attaching operation the bulging portion is laid down in the cavity of the shoe bottom so as to insure attachment of the outsole at all points without undesirable gaps.

Shoe locking mechanism To insure against dislocation of the shoe by the contact therewith of the heel and toe gages 128, 158, locking or holddown means is provided for clamping the toe end of the shoe against the toe pad 58 (Figs. 4 and 6) prior to the operation of the gages. The pin-and-slot connection between the lever 198 and the connecting rod 200, on the one hand, and the similar connection between the lever 224 and the connecting rod 226, on the other, provide for lost motion of the connecting rods, upon downward swinging movement of the main operating lever 204, before actuating the levers 198, 200 to cause swinging movement of the pairs of arms 184, 186 and 208, 210 to move the gages 128, 158 toward the heel and toe ends of the shoe and sole. It is during the time interval provided by this lost motion that the shoe locking mechanism is operated to lock the shoe at each station against the toe pad.

The means provided for this purpose comprises a Bowden wire 248 (Figs. 3 and 4) attached at one end to a pin 250 secured in a block 252 fixed to the rocker 38. A light compression spring 254 on the upper end of the wire 248 bears at its upper end against the under surface of the block 252 and at its lower end against the bottom of a bore provided in a housing 256 secured to the block 36. At its lower end the wire is attached to the lower end of a substantially vertical lever 258 (Figs. 5, 7 and 8) the upper end of which is fulcrumed on a shaft 260 journaled in a bracket 262 secured to the machine frame. On the same shaft 260 is also fulcrumed a lever 264 which is pivotally connected by a link 266 to the main lever 204 (Fig. 5). A pawl 268 pivoted on the lever 264 is arranged to cooperate with a ratchet wheel 270 keyed to the shaft 260 to move the lever 258 in a direction to pull the wire 248 down and lock the rocker 38 and the shoe mounted thereon. The pawl 268 is normally held out of engagement with the ratchet wheel 270 by an abutment screw 272 extending from a bracket 274 secured to the machine frame. A friction disk 276 of fibrous material (Fig. 8) is interposed between the ratchet wheel 270 and the lever 258. A similar disk 278 is interposed between the lever 258 and a disk 280 keyed to a spring loaded friction clutch member 282 which is pinned to the shaft 260.

The arrangement is such that when the main operating lever 204 is moved counterclockwise by the downward movement of the piston 232, the link 266 causes the lever 264 to turn clockwise (as seen in Fig. 5) about the shaft 260, causing the pawl 268 to swing in the same direction to disengage it from the abutment screw 272, whereupon a spring 284 on the lever 264 urges the pawl into engagement with the teeth of the ratchet wheel 270 to rotate the wheel clockwise. By the rotation of the ratchet wheel in this direction the lever 258 is moved clockwise, or to the left of Fig. 5, pulling the wire 248 downward to tilt the last spindle carrying rocker 38 against the resistance of the spring 254- (Fig. 3), so as to force the toe end of the shoe against the toe pad and lock the shoe against displacement by the gages 128, 158. When the rocker 38 is thus tilted, the pins 96 which, as shown in Fig. 3, are normally held against the collar 98 on the screw 92 by the spring 254 surrounding the Bowden wire 248, are moved slightly to the left away from the collar, and are returned into engagement with the collar when the shoe is unclamped at the end of a sole attaching cycle. During the continued downward swinging movement of the main operating lever 204 after 013613'.

Pressure applying mechanism After the shoe at each station has been locked against displacement in the manner just described and the outsole thereon has been positioned by the gages 128, 158 in register with the shoe bottom, the soles, which will have been previously coated with a pressure-responsive cement along their margins, are pressed against the shoe bottoms, which also will have been coated with a similar cement, to effect their permanent attachment. The pressure applying means comprises a pressure pad 286 (Fig. 6), of known construction, carried by a pad box 288 (Figs. 1, 2, 4 and 6) provided for each station of the machine. Each pad box 288 is fulcrumed at its lower end at a point midway of its length for rocking movement about an axis extending transversely of the shoe, on trunnions 290 mounted in depending ears 292 of a yoke 294 extending widthwise of the machine.

Referring more particularly to Fig. 6, the portion of the yoke 294 supporting each pad box has secured to it by bolts 296 a block 298 having a lower arcuate surface with which a complementally shaped upper surface of an upwardly extending portion 300 of the pad box is arranged for frictional engagement, the two surfaces being concentric with the axes of the trunnions 290. A'compression spring 302 bearing at its upper end against the underside of the yoke 294 and at its lower end against the bottom of a bore provided in the portion 300 of the pad box initially maintains the arcuate surfaces of the block 298 and the portion 300 separated slightly to permit the pad box to rock about its trunnions 290 upon engagement with the sole to adjust the pressure pad to the contour of the sole and shoe bottom. When the pad box is operated to cause the pressure pad to press the sole against the shoe bottom, the spring 302 is compressed and maintains the arcuate surfaces of the block 298 and the portion 300 of the pad box in frictional engagement and yieldingly resists filrther rocking movement of the pad box. Initial rocking movement of the pad box in either direction is limited by engagement of shoulders 304 projecting from the upper surface of the pad box with abutment plates 306 secured by screws 308 to the blocks 298. Two pairs of leaf springs 310, one pair at the front and one pair at the rear of each pad box, are provided to centralize the box on its trunnions and to equalize the pressure exerted by the pressure pad on the sole. The springs 310 are secured at their upper ends by bolts 312 to ears of the yoke 294 and bear at their lower ends against shoulders on the portion 300 of the pad box.

The yoke 294 is pivoted for lateral swinging movement to equalize the pressure exerted by the pressure pads 286 widthwise of the shoe bottom on pins 314 (Figs. 1 and 2) mounted in the upper, bifurcated end portions of a pair of substantially parallel arms 316, the lower ends of which have a ball-and-socket connection to trunnions 318 mounted in the opposite'ends of a pressure equalizing lever or whifiietree 320 extending widthwise of the machine and fulcrumed at a point substantially midway of its length on a shaft 322 mounted in downwardly extend ing lugs 324 of the main operating lever 204. Spring loaded pins 326 extending downwardly from the opposite ends of the main operating lever 204 bear against the occupy an inclined position, as shown in Fig. 1.

whifiietree 320, whereby upon downward swinging move ment of the lever 204 the whiflietree may rock yieldingly about the shaft 322 to equalize the pressure exerted by the two pressure pads 286 on the sole at each station of the machine.

In'the normal position of rest of the machine, the arms 316 supporting the pad box carrying yoke 294 When fluid is supplied to the upper end of the piston 232 and the main lever 204 is moved counterclockwise downward, the arms swing about their trunnions 318 forward, or counterclockwise, to a substantially vertical position, from which they thereafter move downward to bring the pressure pads 286 carried by the pad boxes 288 into position to press the outsoles against the shoe bottoms. Movement of the arms 316 from their inoperative to their operative positions is guided by a roll 328 mounted on each arm and engaging in a forwardly and downwardly curved cam slot 330 formed in a plate 332 secured to the machine frame at each side of the machine. As the pad boxes 288 are moved downward by downward movement of the arms 316, the pressure pads 286 first engage the tops of the heel and toe embracing bands 128, 158 (see Fig. 6). Upon continued downward movement of the pad boxes, the brackets 144 and 168 and the pairs of parallel links 148 and 172 are moved, against the resistance of the torsion springs 153 and 178, from the positions shown in Fig. 6 to those shown in Fig. 4 in which they are in substantial longitudinal alinement with the brackets 152 and 176 on which the pairs of parallel links and the gage actuating arms 184, 186 and 208, 210 are pivoted, and in which the top edges of the gages are substantially in longitudinal alinement with the upper surface of the heel and toe ends of the sole. During their downward movement the gages 128, 158, which remain at all times in engagement with the outsoles, aid by their frictional drag on the outsoles in effecting 'a preliminary spotting of the heel and toe end portions of the outsoles to the shoe bottoms, thus insuring against possible displacement of the outsoles by action thereon of the pressure pads.

Shoe ejecting mechanism At the end of a predetermined cycle of operations of the machine, the main lever 204 swings upward or clockwise, as seen in Figs. 1 and 5, to return the pad boxes 288 to their initial positions and to cause the gages 128, 158 to be retracted to their inoperative positions. As the gages are moved out of engagement with the shoes after the attachment of the outsoles, the shoes are automatically ejected from the two stations of the machine and may be received in suitable trays or hoppers (not shown) conveniently. located on the machine.

For thus ejecting the completed shoes there is provided mechanism comprising an ejector plate 334 (Figs. 3 and 10) hingedly secured by a pin 336 to the top of the last spindle carrying rocker 38. Depending from the plate 334 is a lug 338 to which is attached one end of a Bowden wire 340 the other end of which is attached to a horizontally extending lever 342 (Figs. 5 and 9) fulcrumed on a shaft 344 supported in a bracket 346 secured to the machine base 20. Also fulcrumed on the shaft 344 is the upper end of a vertically extending lever 348, to the lower end of which is pivotally connected by a pin 350 one end of a latch 352. The levers 342, 348 constitute a bell crank of variable angle adjustable by means of a set screw 354 threaded through a horizontally projecting arm 356 of the lever 348 and abutting against the under surface of the lever 342.. A spring 358 attached at one end to a pin 360 on the lever 342 and at its other end to the pin 350 mounting the latch 352 on the lever 348 tends to maintain the two levers in their adjusted angular relation. A spring 362 attached at one end to the arm 356 and at itsoppositeend to an arm 364 secured to the bracket 346 maintains the bell crank 342, 348 against the lower end of an abutment screw 366 threaded through the arm 364. The free end of the latch 352 has a nose portion which normally rests on an eccentric pin 368 carried by a shaft- 370 supported in a bracket 372 secured to the machine base. A pinion 374 (Figs. 1, and 9) carried by the shaft 370 meshes with a gear segment 376 bolted to an extension 378 of the main operating lever 204. A tension spring 380 attached at its upper end to a pin 382 projecting from the lever 348 and at its lower end to a pin 384 on the latch 352 maintains the latch normally in engagement with the eccentric pin 368. The arrangement is such that when the main lever 204 swings downward, the gear segment 376 rotates the'pinion 374 clockwise and the eccentric 368 is moved out of engagement with the nose portion of the latch 352. During the reverse swinging movement of the main lever 204 the gear segment 376 rotates the pinion 374 counterclockwise and the eccentric pin 368 by engagement with a corner of the nose portion of the latch 352 moves the latch toward the left of Figs. 5 and 9, causing the bell crank formed by the levers 348, 342 to swing clock'wise, thereby pulling the Bowden wire 340 downward and actuating the ejector plate 334 to swing upward, from the position shown in full lines in Fig. to the position shown in broken lines, to remove the last and the shoe mounted thereon from the last pin 42. After ejecting the shoe the plate 334 swings downward by gravity to its original position to permit loading of another shoe.

Electrical controls and operation of machine A cycle of operation of the machine will now be de scribed with particular reference to Figs. 1 and 5 and the wiring diagram of Fig. 13.

The electric motor M is started by closing the starter switch 244 (Figs. 2 and 13), thereby energizing a relay C (Fig. 13) and closing contacts CA and CB, to establish a holding circuit for the motor, which will continue to run until stopped by opening of the normally closed stop switch 244.

To attach an outsole O to the bottom of a shoe S mounted on a last L at each of the two operating stations of the machine, the operator places the last, with a shoe mounted thereon, in inverted position on the last spindle 42, with the toe end of the shoe resting against the toe pad 58. He will next make such adjustments of the heel and toe supports as may be required for the size, style and heel height of the particular run of shoes to be operated on, by turning the screws 30, 46, 68, 80, 92 and 122 (see Fig. 3), in the manner previously described. The operator will then place on the cemented bottom of each shoe a prefitted and cemented outsole. Inplacing the outsoles on the shoe bottoms, no particular care need be taken to register them with the shoe bottoms, such registering between the soles and the shoes being the function of the gages 128, 158.

To initiate an operating cycle of the machine the operator depresses a pair of buttons 386 (Figs. 2 and 13) to close a pair of switches 386a and a pair of switches 38Gb included in an electric circuit controlling the operation of the fluid pressure mechanism comprising the piston 232 to which the operating lever 204 is connected (Figs. 1 and 5). The switches 386a, 38617 are housed in boxes 388 secured, one at each side of the machine, to a bracket 389 bolted to the casting 22. Closing of the switches 3861), which are connected in parallel, causes current to be carried by line 3860 (Fig. 13) to contact KlB of a relay K1. Since the contact KlB is open, closing of the parallel switches 3861) is 'Without elfect at this time. Closing of the switches 386a, which are connected in series, causes current to be carried by line 386d and through the closed upper contacts 390a of a microswitch 390 (the function of which will shortly be explained) to the relay coil K1, energizing this relay and closing the contacts KIA and KIB. Closing of contact KlB now causes current to pass from the parallel switches 386b to the relay K1 to maintain it energized, so that the operator may now release one, but not both, of the switch buttons 386.

Closing of the relay contact KIA completes a circuit from a line-386e to energize a solenoid 392, the armature of which is connected to the stern 394 of a pilot valve 396, and actuates the valve to admit pressure fluid to the lower end of a control valve 398 which is moved upwardly from the position illustrated. This permits fluid to flow through the pipe 236 (Fig. 5) into the upper end of the cylinder 234 to cause the piston 232 to move downwardly and initiate downward swinging movement of the operating lever 204 which actuates the gage mechanisms, the shoe locking means, the pressure applying means, and the shoe ejecting means in timed relation during an operating cycle of the machine. It will be noted that,-the switches 386a being connected in series, the operator must depress both buttons 386 to initiate operation of the machine and hold at least one of them depressed for a length of time sufiicient to allow the pad boxes to be moved into a position in which there is no longer danger of the operators hands being caught in the machine.

Soon after the beginning of downward swinging movement of the lever 204 the shoe locking mechanism at each station, comprising the Bowden wire 248 (Figs. 5 and 7), the lever 264, the pawl 268 and the ratchet 270, is operated to clamp the toe end of the shoe against the toe pad 58. Pressure of the toe end of the shoe against the toe pad actuates a spring loaded rod 400 (Figs. 3, 4 and 5), the upper end of which bears against the underside of the slide 52 (which is spaced from its supporting bracket 50 an amount sufiicient to permit the slight movement necessary to actuate the rod), and closes a microswitch 402 to energize relay K4 and, by closing the relay contacts K4A and K4B, to complete a holding circuit for maintain- .ing the relay K1 and the solenoid 392 energized even if the switches 390 and 402 should be opened. However,

at this stage the operator must still maintain pressure on at least one of the switch buttons 386. It will be noted that energization of the relay K4 to complete the hold- ,ing circuit cannot take place unless there is present a .shoe at each station and unless the shoes at both stations have been properly locked against the toe pads 58.

As the main operating lever 204 continues to swing downwardly, the gages 128 and 158 at each station are ac- .tuated, through the connections 200, 198 (Figs. 1, 3, 4 and -5) to the parallel arms 184, 186 of the heel end gage mechanism and the corresponding connections 226, 224 to the parallel arms 208, 210 of the toe end gage mechanism, to move into engagement with the heel and toe ends of the shoes and soles to position the soles in register with the shoe bottoms. 'By the downward swinging movement of the lever 204, the arms 316 which support the yoke 294 on which the pad boxes 288 are fulcrumed are moved from their normally inclined position of Fig. 1 to a substantially vertical position to locate the pad boxes in the position in which the pressure pads 286 will engage the .top .edges of the gages 128, 158. Near the end of the downward swinging movement of the lever 204, a cam face 404 onthe gear segment 376 (Figs. 1 and 5) connected to the lever actuates an arm 406 which controls the microswitch 390 (Fig. '13). This switch is housed in a box 408 (Figs-1 and 5) mounted on a bracket 410 secured to a front cover plate of the machine base. Acftuation of the arm 406 causes the upper contacts 390a .(Fig. 13) of the microswitch 390 to be opened and the lower contacts 39% to be closed. Crurent now passes through the normally closed contact KBTDA of a time ,delay relay K3TD and energizes this relay and also a relay K2, closing relay. contact K2A to complete a circuit throughthe now closed relay contacts KIA, switch contacts 390b, relay contacts K3TDA, K2A, K4A and K4B to maintain the relay K1 energized, allowing the operator now to release both switch buttons 386. During the final phase of the downward swinging movement of the operating lever 204, the pad boxes 288 are moved into position to apply pressure to the soles to bond them to the shoe bottoms, the gages 128, 158 being depressed by the pad boxes to the level of the upper surfaces of the soles while remaining in engagement with the soles and shoes until the end of the sole attaching cycle. The time delay relay K3TD is controlled by a timing device (not shown) which deenergizes it at the end of a predetermined period to break the holding circuit through the relay K1, the contacts 390a of the microswitch 390, the contacts KIB and KIA and deenergize the solenoid 392. Deenergization of the solenoid will move the valve stem 394 down so that the fluid from the upper end of the cylinder 234 will be exhausted and fluid will be admitted to the lower end of the cylinder to cause upward movement of the piston 232, thereby causing the operating lever 204 to swing upwardly clockwise (as seen in Figs. 1 and 5) to move the pad boxes out of pressure applying position, provided both switch buttons 386, which control the parallel switches 386b, have been released, thus safe-guarding against the possibility that the operator might tie down one of the switch buttons to free one hand and thus defeat the objective of requiring him to use both hands to start the,

machine.

During prolonged periods of idleness of the machine, minute leakage of pressure fluid from the lower end of the cylinder 234 may cause the arms 316 which support the pad box carrying yoke 294 to drift into a vertical position and bring the pad boxes down. To maintain the arms 316 in their inclined position, as shown in Fig. 1, during the inactivity of the machine, there is provided an upwardly extending arm 412 (Figs. 1 and 5) pivoted at its lower end by a pin 414 to the lever 204 and at its upper end by a pin 416 to the machine frame. A shorter arm 418 is pivoted at its lower end on the pin 414 and at its upper end by a pin 420 to the lever 204. The arms 412, 418 are maintained in the positions illustrated in Fig. 5, when the machine is inoperative, by a spring 422 connected at one end to the arm 412 and at its opposite end to the machine frame, to resist downward swinging movement of the lever resulting from the escape of pressure fluid from the cylinder.
